T: i am sure i beat UTG and i think mosttime i ahed vs fish if he checks here.

R: clera valuebet and get minrasie from fish, i beat only bluff or tricky play AA or AK - but he is super passiv, and i get reads he cc TP, minrasie AA on the flop even i must be good 7:1 this is hard decidon for me?

That's kinda sick if you have such reads on him that he even is playing passively his overpair. Therefore I might even prefer just folding on river against that kind of player, I see just most of the time at least 7x from his side.

Of course we need like 16% equity, although even against that kind of range we ain't getting it that easily:
